Title: Conversion studies for a more peaceful world

As an independent, non-profit organization, BICC (Internationales Konversionszentrum Bonn—Bonn International Center for Conversion) deals with a wide range of global topics in the field of peace and conflict research centering on Conversion Studies. Our vision is a more peaceful world. Our mission is to conduct critical, problem-oriented, policy relevant research in response to the problems posed by organized violence. To do so, we engage in active exchanges with scholars and politicians as well as stakeholders in everyday practice and civil society. As a think tank, BICC seeks to engage in a dialogue with NGOs, governments, private organizations, research institutes and universities and well as with interested individuals. The talk will give an overview about research themes and projects conducted at BICC.

Date: Wednesday, April, 29th, 2015; 12:00 – 12:30
Place: Techno-Z, Z_GIS meeting room: SC30EG0.E07 (Schillerstraße 30, building 15, ground floor)
Presenter: Florian Albrecht (PhD candidate, Researcher, Department of Geoinformatics – Z_GIS, Salzburg University)
Title: Indoor navigation and 3D modelling with the Google Project Tango tablet Recently,

Google has come up with a tablet called “Project Tango” that integrates different sensor technologies by using concepts from robotics and visual perception. The resulting tablet improves its location measurements from the Inertial Measurement Unit (IMU) by correcting them with motion tracking information from its fisheye camera view. Additionally, the tablet’s RGB camera has been enabled to perform depth perception which allows to generate textured 3D indoor models by filming all surfaces that shall be represented in the model. More details about the technology can be found on https://developers.google.com/project-tango/. At the Department of Geoinformatics, we intend to explore a variety of research and development topics with the Developer Tablet including: API programming, Image Analysis/Point-Cloud Analysis, Indoor Navigation, Augmented Reality, Facility Management and other application domains. The talk will present the already identified potential of the technology and will discuss opportunities for involvement in its further exploration.

Prof Thomas Blaschke elected to Austrian Academy of Sciences

Prof Blaschke on April 17 was elected as a corresponding member into the Austrian Academy of Sciences (ÖAW). This is a significant recognition of the impact of his scientific work on the highest level, and a huge honour for Z_GIS, the Doctoral College and the University of Salzburg to have Prof Blaschke among its leaders.

Due to the strictly limited number of national Academy of Sciences members only few scientists are elected into its ranks every year, as every nominee needs to be confirmed on multiple levels, listed within the available places, and is required to receive a majority of votes by the current membership.

We at Z_GIS are proud of this achievement - congratulations!

New Journal Paper on ABIA now available

The article Towards a framework for agent-based image analysis of remote-sensing data has been published by the International Journal of Image and Data Fusion in March.

The article introduces a framework for agent-based image analysis (ABIA) of remote sensing data. Robust and transferable object-based solutions for automated image analysis, capable of analysing sets of images or even large image archives, are still rare. Object-based image analysis (OBIA) rule sets bear a high potential of transferability. The high complexity of image content however often makes human interaction necessary.
In order to automate the adaption and adjustment procedures, the authors (Hofmann, Lettmayer, Blaschke et.al) investigated the coupling, extension and integration of OBIA with the agent-based paradigm of ABIA. They show that even with simple designed image object agents (IOAs) enabling agent-based control and simulation, an improvement of the initial classification is possible. The authors demonstrate the potential of ABIA to autonomously adapt image objects to unknown imaging situations. Link to article

Award for Excellence in Teaching @ Z_GIS | Congratulations!

Christoph Traun and Martin Loidl from Z_GIS have received the 'Award for Excellence in Teaching' for their class 'Geo-Communication'.

The 'Award for Excellence in Teaching' of the University of Salzburg has been presented to the 4 finalists from the summer semester 2014 and winter semester 2014/15 - with Christoph and Martin taking the top spot with their final presentation. Initial nominations for this award come from students, leading up to an assessment by an expert jury. On April 15, the prize was awarded at the "Day for Teaching 2015".

Congratulations! 

They follow in the footsteps of Z_GIS’ Dirk Tiede, who previously had won this prize for his 'Design and Development of Applications' class.

Special Issue: Earth Observation for monitoring NATURA 2000 Habitats

A special issue of Elsevier´s "International Journal of Applied Earth Observation and Geoinformation" provides insights into how Earth Observation (EO) technology supports authorities in monitoring NATURA 2000 habitats.

This Special Issue is a joint outcome of the two complementary EU projects MS.MONINA and BIO_SOS. Both projects have prepared the ground for establishing multi-scale services for habitat and biodiversity mapping based on satellite information.

MS.MONINA, coordinated by the Department of Geoinformatics - Z_GIS at the University of Salzburg fosters the use of Copernicus space and in-situ data infrastructure for supporting NATURA 2000 monitoring and management. From a multi-scale perspective it provides on-demand geospatial information to users such as local, national and European authorities.

The compilation of 17 original papers demonstrates the multi-faceted advantages of EO data in support of biodiversity, ecosystem and habitat monitoring. This is achieved especially with respect to the time and cost effectiveness of the tools. The published papers also show the multi-temporal/multi-scale capabilities for monitoring conservation targets. The journal special issue provides an overview of the state-of-the-art and challenges in remote sensing for mapping natural habitats and their conservation status.

The articles are accessible under open access for six months:
